h = 21cm
CSA = 176cm²
2πrh = 176cm²
2 × 22/7 × r × 21 = 176
2 × 22×r×3 = 176
132×r = 176
r = 176/132
r = 1.333
r = 1.34cm

Radius of cylinder = 4/3 cm if The curved surface area of a cylinder is 176cm² and it's height is 21cm
Step-by-step explanation:
The curved surface area of a cylinder is 176cm²
CSA - Curved surface Area
CSA of cylinder = 2πrh
r = Radius of cylinder = ?
h = height of cylinder = 21 cm
π = 22/7
=> 2 (22/7) * r * 21 = 176
=> 44 * 3r = 176
=> 3r = 4
=> r = 4/3
Radius = 4/3 cm
Radius of cylinder = 4/3 cm
